Vision: She is, as they say, right in it now that Pony Van Helsing is aware of her condition. Given that his prescription is twenty ccs of stake through the heart, I should think that Luna offers Twi her best shot of surviving this crazy toboggan ride.

Originality: While we're obviously looking at a person undergoing vampirism told from the vampire's side, there's enough of a connection to the series to make it novel.

Technique: The conversation she and Spike had as they planned their escape reminds us that being a monster isn't as black and white as Neuron would have us believe.

Impact: I wonder what it is that Luna is about to do. Odds are that we're looking at getting herself a special student.
